Custom Long text from Staging to Active area

Dear All,

I have a requirement to add a custom long Text for Custom Text ID for MDG-M, The screen look Similar as to Standard (BSCDATTXT, PURCHTXT, QINSPTXT).

To fulfill This I have created a Custom Entity at data model level MDG-M

. Generate Model specif structure

. Done SMT Mapping

. Created a Composite UIBB and Linked with Standard UIBB.

. Create a wire for this

by doing my custom long text UIBB is visible as extra tab on MDG-M screen. I am able to add Long text for my custom Text id .

But this long text on final approval is not moved from Staging to active area.

Please let me know do I need to enhance Access class for this Or I need to Create new access class add to data model for that custom entity.

If any one has worked on this please let me know how to move data from staging to active area from custom long text.

Regards,

Riyajuddin
