Long Material Number (>18 symbols) within ECM

61 Views

Good Day colleagues,

We have faced the problem after extension of material number length to 40 symbols. Please see detailed description below.

Preconditions:

1) Long Material Numbers (>18 symbols) are used in the system

2) Note 998183 was installed in the frames of support package SAPKA70017(link: [https://websmp130.sap-ag.de/sap(bD1ydSZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=998183] )

3) Engineering Change Management component is used.

Problem description:

In transactions cc01/cc02/cc31/cc32 when processing long material numbers (>18 symbols) system works correctly only when material exists in the system. When trying to enter non-existent material number (with length>18 symbols) in the change master record, system checks that there is no such material exists in the system and truncates the material number to the length of 18 symbols u2013 in other words it puts truncated to 18 symbols material number in the RC29A-MATNR field of the change master record and that is incorrect. Due to this error system transfers the truncated version of material number to AEOI table (field OBJKT) though this field dimension is 40.

The same problem appears when trying to process such material (non-existent material with long number>18 symbols) in the BOM tab of the change master record. In this case AEOI-OBJKT field has dimension 40 symbols, but positions 19-22 of this dimension are reserved for WERKS value and 23-40 positions are reserved for alternatives numbers. It looks like this internal structure (AEOI-OBJKT) for BOMs was not extended for long material numbers.

The goal:

To have an ability to process correctly non-existent long material numbers (>18 symbols) in the change master record (both in the tabs of Material and BOM).

Thank you in advance for any proposals.
