MARA-EXTWG Field length

[kiran_k8]

Folks,

We have a requirement to extended the field length of External Material Group (MARA-EXTWG) and its description (TWEWT-EWBEZ).

The only option I see

1.is to create a  Z domain with the desired length and replacing the standard  domain of the data element EXTWG with Z domain   which I feel is not advisable.(Whereused list of EXTWG data element resulted in 71 hits).

2.create an append structure in MARA with zextwg (with a custom data element of desired length) and populate it via an exit.

Kindly share your expertise on the 2nd approach.

Hi Kiran

Never modify the standard fields and domain. If you do a where used list for them you will see so many hits. By the way what is the purpose of increasing the length?? You can go by either append structure but this you need to find corresponding BAPI/FM etc. You can also create a custom table containg these fields. The question is how do you want tp use them???

Nabheet,

Yeah,I intend to go with the 2nd approach and hence looking for more info.

Currently,I intend to replace the standard fields in MM01 (screen level too ) by extending the length from 18 to 32 for EXTWG and from 20 to 50 for its description.

My Query is once we add the field in MARA using append structure,will this new field will be available in Material Master Maintenance Field group selections (OM* transaction codes) so that we can replace the existing field with the new field at the screen level.
