APPEND STRUCTURE

[Former Member]

hi!

If a standard table has a category "cannot be enhanced" and I change it to "can be enhanced" and then add an APPEND Structure.

If a patch or an update is done by SAP will my APPEND Structure be overwritten and dissapear?

regards

Baran

hi baren,

1. Good question.

2. Suppose the table structure is :

10 fields.

3 fields (of our appended structure)

3. During upgrade,

suppose sap has added 2 fields (11,12),

then

SPECIAL TRANSFORMATION takes place

and the new table will be now

10 fields.

2 fields (of upgrade)

3 fields (of our appended structure)

Hello Baran

I would assume that the category "cannot be enhanced" is simply used as a "on/off" switch that either allows to append a table or not. If so, nothing should happen to your APPEND structure during patching or upgrading.

However, since I am not sure about this I would recommend to make a simulation:

(1) Create a customer table (Z...) with category "can be enhanced".

(2) Append your customer table.

(3) Transport the appended table to a QA system.

(4) Change the category to "cannot be enhanced" in DEV system. If the system allows this, then transport the changed table definition to your QA system.

I would expect that a SAP standard table will behave quite similar in this scenario like your customer table.
