Generate Data Model Specific Structures in MDG

[Former Member]

Hi ,

Is it possible to change property of any Standard Type 1 Entity and Generate data model specific structures ?

E.g : In MDG-F there is Type 1 entity " Account " . We want to change the data element USMDZ1_ACCOUNT with custom data element Z1ACCOUNT . We changed data element and activated data model . But when we try to generate data model specific structures SAP does not allow us to do it and we got below message . Are there any system settings which is making us not to generate data model specific structures ?

Hi

No, there aren't. The check of customer vs. SAP namespace is hardcoded.

With the change of the data element for an SAP entity (ACCOUNT in data model 0G), you already did a modification.

Thus changing the structures generated and shipped by SAP is a follow-up modification (and maybe also some BAdI implementations, feeder classes, whatever).

Hi,

as already mentioned by Ingo, this kind of change is considered as modification of the data model and should not be done. If you really need this, structure generation does not help. You need to modify affected structures (there are plenty of them!) manually, too.

Please keep in mind that with this modification you'll loose SAP support and might run into issues as soon as you plan to apply any newer MDG release or support package.

Best regards

Do we need to regenerate data model specific structure post upgrade?

Hi Ramesh

Regeneration of model specific structures is the pre-requsites for any enhancement in data model.

Due to customer specific enhancement DDIC structures are needs to generated so that we perform SMT (Mapping) for it and also it becomes available attributes for enhancing user interface also.

In your case though yoy are not adding any entity or attribute but there is enhacement for updata of data element. This data element must appears to assigned field in DDIC structure.So we need to perform regeneration of model specific structures.

Can I ask one question, any reason behind change of data element for ACCOUNT?
