Hello

The quantity of a schedule line generated by MRP depends on your lot sizing procedure, defined on tab MRP 1 of the material master.

Dear Ceatano,

I have checked already, but it seem OK. Many other materials with same value but they are OK.

Have you got any other suggestion?

Thank you,

The fact that other materials with the same settings are working does not tell anything to me. On different scenarios you will have different results with the same settings.

Please share a screenshot of tab MRP1 of the material master.

when planned order created in MRP, is then replanned in capacity requirements planning (CRP), the capacities of the manufacturing operations will produce a feasible planned order.

How will this CRP affected the planned order to make it feasible, does it over-write the in-house production time if it's maintained in the Material Master?

Hello

If I understood your requirement correctly, you want to understand why there is a difference between the quantity displayed on MD04 and the schedule ling open quantity, am I right?

One possible reason is an inconsistency on the field DABMG of the schedule line, since this field controls the MRP reduced quantity. Take a look on the section Inconsistent purchase order, inbound delivery or shipping notification of the following WIKI and check if you can find the inconsistency:

https://wiki.scn.sap.com/wiki/display/ERPMan/Inconsistencies+for+planning+elements+and+display+problems+on+transaction+MD04

Another possibility is that you are using a BAdI (such as MD_CHANGE_MRP_DATA) to influence the MRP calculation.

Regards,

Caetano
