    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.

    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,
