SQLSCRIPT identifier must be declared CLIENT

[hassin]

Hallo,

I'm trying to program a class where I use a CDS View as a source.

With a table function I would like to use the result in another CDS.

My problems started with the client handling and know I'm stuck with the client identifier.

After fixing one error after an other it feels like I'm running in circles.

That's why I hoped that someone could help me?

It would be great when you could check my programming (in attachment) and give me a feedback.

Kind regards

Hassin

So, you have:

1. CDS view ZIB_KAPA = view on table KAPA
2. Table function ZTF_PROLINEDATE = AMDP method which reads CDS view ZIB_KAPA
3. You want to call the table function and pass parameter CLIENT1 = any client number you wish

What is your issue?
