FAQSolution

1. Question:What is the difference between planned independent requirement consumptionand planned independent requirement reduction ?

Answer:The consumption reduces planned independent requirements dynamically,whereas the reduction physically reduces the planning quantity and increases thewithdrawal quantity accordingly.

For example: You create a planned independent requirement with 100 pieces.This planned independent requirement is consumed against a sales order with 10pieces. The planning quantity and withdrawal quantity remain the same (seeMD63) but the planned independent requirement is displayed in thestock/requirements list (MD04) with the quantity 90. The independentrequirements reduction occurs when you post the goods movement, in this case,

with the goods issue for the sales order. The planning quantity of the plannedindependent requirement is reduced to 90 pieces and the withdrawal quantity isincreased from 0 to 10 (see MD63). In the stock/requirements list, the plannedindependent requirement is still displayed with 90 pieces despite the reducedplanning quantity because when you post the goods issue, the customerrequirement against which the planned independent requirements had beenconsumed also disappears.2. Question:Which consumption parameters (Consumption mode/consumption period) aretaken into account?

Answer:

The parameters maintained in the material master (material requirements planningview 3) have the highest priority. If you do not specify a consumption mode, thesystem uses the consumption parameters from the MRP group that is assigned tothe material. If a consumption mode is not specified there, the consumption modeis set to '1' by default (backward consumption only) with a (backward)consumption period of 999 days. This means that the consumption cannot bedeactivated because the consumption parameters have not been maintained. Theconsumption periods are calculated in workdays.3. Question:

Where can I check whether a planned independent requirement is consumed oragainst which requirements it is consumed?

Answer:a) In the total requirements display (MD73), you can display details about whichassignment requirements (customer requirements, dependent requirements,reservations, calls for stock transfers) are used to consume a plannedindependent requirement.


3/34

b) In the stock/requirements list (MD04) or the MRP list (MD05), plannedindependent requirements are displayed with their planning quantity minus theconsumed quantities. Planned independent requirements that have beencompletely consumed are not displayed.c) In the planned independent requirements maintenance (MD61, MD62, MD63),you can display the consumed quantities on the 'Schedule lines' tab page (Menupath 'Settings' -> 'Consumed quantity').

4. Question:Why is a change to the strategy group or a consumption-relevant change inCustomizing ineffective?

Answer:

When you create a new planned independent requirements item, Customizingdata is stored in the corresponding database table (PBIM or PBID) and notadjusted later. When you delete and recreate a planned independentrequirements item in Transaction MD62, the changed Customizing data is not

taken into account either because the existing data record receives only a deletionindicator and is then reactivated. To physically delete the data record, you mustcompletely reorganize an existing planned independent requirements item(Transactions MD74, MD75, MD76). With the new entry, a new data record iscreated with the current Customizing settings (see Note 166267).Changes to the consumption mode and consumption periods are immediatelyeffective.5. Question:Which settings are required to consume calls for stock transfers with plannedindependent requirements?

Answer:a) For the consumption of a planned independent requirement with finalassembly, the 'Mixed MRP' indicator must be set to '1' in the material master.The consumption indicator of the planned independent requirement must be setto '3' (see the 'Item' tab page in Transaction MD63). When you create a plannedindependent requirement, the system uses the default value from CustomizingTransaction OMP6.b) For the consumption of a planned independent requirement without finalassembly, the 'Mixed MRP' indicator must be set to '3' in the material master.The consumption indicator of the planned independent requirement must be setto '3' (see the 'Item' tab page in Transaction MD63). When you create a planned

independent requirement, the system uses the default value from CustomizingTransaction OMP6.c) A consumption with planned independent requirements of a planning materialis not possible.

6. Question:How I can flexibly define against which MRP elements planned independentrequirements are consumed?

Answer:


4/34

Use 'Planning consumption indicator' on the item view of the planned independentrequirements maintenance (MD61, MD62, MD63) to determine whether a plannedindependent requirement is consumed against customer requirements,reservations, dependent requirements and calls for stock transfers. TheMD_PIR_FLEX_CONS BAdI, which allows a more detailed differentiation basedon the MRP elements, has been implemented for Release 4.7. In previousreleases, you can implement this BAdI using modification Note 127370.7. Question:The availability check against planned independent requirement returns anunexpected result. What has to be checked?

Answer:Note 622299 describes the general procedure and also frequently askedquestions.8. Question:Why are monthly or weekly requirements not consumed even though the

assignment requirement is in the same period?

Answer:Planned independent requirements that are created as monthly requirements orweekly requirements are internally set to the first workday of the period. This is therequirements date in the stock/requirements list and the relevant date for theconsumption.

For example: In the material master, a 10 days backward consumption is defined. A monthly requirement for JAN/2005 is created. The first workday of the month isJAN/03/2005. A customer requirement with the requirements date JAN/20/2005 is

not consumed because there are more than 10 workdays between the customerrequirement and the planned independent requirement. For consumption andreduction, it does not make any difference whether the planned independentrequirement was created as the JAN/2005 monthly requirement or as theJAN/03/2005 daily requirement.9. Question:I am using several active planned independent requirement items. Can I controlthe order in which they are consumed?

Answer:No. Schedule lines for planned independent requirements items with the same

consumption-relevant settings, which only differ in 'Version' or 'Requirement plannumber' for example, are both used for consumption and reduction at the sametime.10. Question:Why is a planned independent requirement not consumed against a customerrequirement even though it is in the consumption period?

Answer:


5/34

It is a prerequisite that the 'Consumption indicator' of the planned independentrequirement (ZUVKZ) corresponds to the 'Assignment indicator' of the customerrequirement (VPZUO) and provides the consumption (values '1', '2' or '3'). You cancheck these values by calling the detailed dialog box for the corresponding MRPelement in the stock/requirements list. The field is not displayed for customerrequirements that do not provide any consumption (VPZUO = ' '). The values arecopied to the corresponding database tables (PBIM/ PBID, VBBE/VBBS) whenyou create the planned independent requirements item or the customerrequirement and they are not adjusted if the planning strategy or Customizingsettings are changed (see question 4)

You must also ensure that the 'Planning consumption indicator' (VERVP) providesa consumption with customer requirements. You can display this on the detaildialog box for the planned independent requirements in the stock/requirements list(MD04) or in the item view of the independent requirements maintenance (MD61,MD62, MD63). Any changes to this indicator affect the consumption immediately.11. Question:What should I do if customer requirements are not consumed because they arenot transferred to the material requirements planning or they have an incorrectassignment indicator?

Answer:The settings of the requirements class that is found (Transaction OVZG) controlthe transfer of requirements to the material requirements planning. If customerrequirements are not create as you want them to be, refer to point 7 of Note547277 and also to Note 207942. These notes describe how the requirementsclass is determined.12. Question:Why are planned independent requirements not consumed against requirementsin storage locations that are planned separately or that are excluded from thematerial requirements planning?

Answer:See Note 545327.13. Question:Can I ensure that customer requirements are consumed only with plannedindependent requirements if the respective requirements types are linked by the

strategy (Transaction OPPS)?

Answer:No. The consumption indicator and the assignment indicator that are derived fromthe respective requirements type are relevant for the consumption (see question10).


6/34

For example: You have assigned two strategies with different plannedindependent requirements and customer requirement types to the planningstrategy group that is used. However, if all requirements types provide aconsumption of a planned independent requirement with final assembly, theplanned independent requirements and customer requirements are both used forthe consumption at the same time.14. Question:I am using the MD_PIR_FLEX_CONS BAdI. Why is an MRP element notconsumed with a planned independent requirement even though this should occuraccording to the implementation?

Answer:The BAdI allows you to determine in greater detail than you can using the previousvalues of 'Planning consumption indicator' which requirements should beconsumed. However, other consumption-relevant settings must also be fulfilled(for example, consumption indicator = assignment indicator for customerrequirements; Mixed MRP for stock transfers).
