Problems in extending MDG-C with a a new resue Table

[Former Member]

Hello List,

i am working on MDG-C 9 on HANA.

I using https://scn.sap.com/docs/DOC-31885 and trying to enhance MDG-C with a new reuse Table.

What is working:

I have the fields on the UI in an new UIBB and when i enter something the data flows from BOL to MDG model and back. So when i enter a value it will be changed in a derivation and the changed value is displayed in the UI.

Not Working

Nothing is saved to staging or read from staging

The following methods are called when working in the UI:

(Handler Class)

IF_MDG_BS_BP_ACCESS_HANDLER~SORT_ENTITIES
IF_MDG_BS_BP_ACCESS_HANDLER~READ_OBJECT_DATA

(BOL)

IF_GENIL_APPL_DYN_META_INFO~IS_CHILD_CREATE_ALLOWED

The following methods are never called when working in the UI:

(Handler Class)

IF_MDG_BS_BP_ACCESS_HANDLER~GET_OBJECT_DATA_BY_ENTITY
IF_MDG_BS_BP_ACCESS_HANDLER~MAP_DATA_2API
IF_MDG_BS_BP_ACCESS_HANDLER~MAP_DATA_2STA
IF_MDG_BS_BP_ACCESS_HANDLER~PREPARE_EI_HEADER_MAP_2API

(BOL)

TRANSFORM_TO_ENTITY_KEY

Any hints? Why are some methods never called?
