Block access to change descriptions on certain material types but keep it open for ALE

[Private_Member_50209]

Dear all,

We have the following scenario:

For certain material types we recieve the materials via ALE from an external system. As the external system controls the short description we need to block the short description from being changed in SAP ECC directly.

What is the best way to accomplish this?

Currently we have a custom field reference group assigned to a set of material types and defined via field control customizings that for this field reference, field group 020 would be read-only.(020 included the short descriptions out of MAKT)

This works fine in online mode, however it seems that this is also blocking updates coming in via IDoc. Now strangly we also have long texts out of STXL blocked via customizing, but here the problem doesn't occur. We can still set those via iDoc updates.

Did anyone experienced similar problems and how were they solved?

Thanks in advance,

Lee

Hi Erik,

what is the settings of your field group 020 for reference MM01/MM02 and MAL1/MAL2? References MAL1/MAL2 are used for ALE, whereas MM01/MM02 are used (obviously) for online mode.

Then there is second customizing which can effect this behaviouor -- each field name is assigned to "ALE field group GR" (double-click the record in OMSR); these field groups can the be assigned to authorization profiles and logical systems (see customizing Predefined ALE Business Processes -> Logistics -> Master Data Distribution -> Integrated Distributed PDM Solution (ID PDM)).

Kind Regards

Hi Tomas,

Thanks for your reply.

The settings for field group 020 are:

- MM01/MM02     => Required

- MAL1/MAL2      => Optional

- ZGRP               => Display

It's via the ZGRP field reference group that we control the access. This because MM02 may change the description on some material types, but not those that are being send via ALE. On those ALE material types we've added ZGRP as the field reference group via OMS2.

I can see that the ALE field group is set to GR_MAKT, however I don't seem to find out what I can do with this. Meaning, I don't see a reason why this would block the short description from being overwritten via ALE.

To me it looks like the field reference group on material type level takes precedence over the MAL1/MAL2 group. Could that be possible? Is there a way to change this?

Best regards,

Lee
