How to download price scales in central contract?

Hi experts!

I hope you will be able to help me.

I need to identify contract items which have price scales maintained in price conditions and download them. I know contract numbers, but have no idea which might contain price scales.

For "standard" contracts I can do this as follows:

From SE16 table A016 I get Condition Record Number for each contract line.

Using Condition Req. Nr. as input for table KONM I get price scales.

Problem lies with central contracts - A016 returns only conditions from main contract level, whereas I need to check plant specific conditions.

Anybody any ideas?

Thanks in advance!
