BAPI_PROJECT_MAINTAIN - E CN 770 Errors occurred during processing

[Former Member]

Hello Experts,

This is related to Project Systems module.

I am creating a Project Definition using BAPI_PROJECTDEF_CREATE bapi and it getting created OK with no issues.

Now for the same project definition (created using above bapi) I am trying to create WBS Elements using bapi BAPI_PROJECT_MAINTAIN.

But I am getting error as "E CN 770 Errors occurred during processing (see error log)"

And error log says:

METHOD OBJECT_TYPE INTERNAL_OBJECT_ID

Update WBS-Hierarchy

Update WBS-Hierarchy

Although I am not using UPDATE method. I am using CREATE method.

Here are the contents of I_METHOD_PROJECT table

REFNUM OBJECTTYPE METHOD OBJECTKEY

000001 WBS-ELEMENT CREATE Y.998

000002 WBS-ELEMENT CREATE Y.998.1

000003 WBS-ELEMENT CREATE Y.998.1 -1

000000 WBS-HIERARCHY CREATE

000000 SAVE

Here are the contents of I_WBS_HIERARCHIE_TABLE table:

WBS_ELEMENT PROJECT_DEFINITION UP DOWN LEFT RIGHT

Y.998 Y.998

Y.998.1 Y.998 Y.998 Y.998.1 -1

Y.998.1 -1 Y.998 Y.998.1

Can anyone tell me where is the problem?

Thanks for all your help!

Check RETURN parameter after BAPI_PROJECT_MAINTAIN. It will give you detailed error information.
