SRM-ECC-SUS PO consistency SRM 5.0

Hi,

We are using SRM Server 5.5 SP12 & ECC 6.0 SP Stack 15

Extended classic scenary is in use.

We have problems with PO Documents when in backend ECC system is there an error.

I mean,the PO is created in SUS even when is not created in ECC(for example, for an FI error).

I know that in SRM 7.0 there is a new functionality to avoid this through SPRO check boxes:

'Display Back-End Messages as Errorsu2019

'Consistency Check Active in Back-End'

My questions are...

- For SRM Server 5.5 is there a similar configuration??

- Or maybe, is an SRM 5.5 support package where I can have that functionality??

Thanks for your time.

Regards

Tania
