Append Structure while Upgradation

[Former Member]

Hello All,

when we extend a standard table with append structure, if we go for system upgradation to higher version what will happen to this extended version?

is this available in the extended version along with the data or it will get deleted?

thx in advance.

hi Sippy,

the append structure will remain the same and the data in it as well. (important is that you keep the naming conventions, ie. each field in the append has to start with ZZ... or YY...)

hope this helps

Hi,

Append structure or Include structure as supported as part of enhancements... Hence they still exits after upgrade..

Only modifications to standard SAP code will vanish...

Hi Sippy,

You can move the append structure using SPAU and SPDD as well as data also.

Basically it is done by basis people.

Thanks,

Hi Eric,]

thx for the reply.

i have a query....

field name should have first character as Z or Y or first two characters as YY or ZZ......

wat happens if we don't follow this naming notation??

[JozsefSzikszai]

it should start with ZZ or YY (as first two characters)

if you don't do that: sometimes SAP introduces standard field names which start with Z (for example: BSIS-ZUONR), if you have an own field like this in your append structure and SAP introduces this into the standard (the chance is small, but you can never know), you have troubles by upgrade. (but if you add an append structure you will get a warning that you have to add field names with ZZ or YY to avoid troubles)
