Financial newby: Combining SAP SRM and ERP Financial Accounting

Question

Hello,
Looking for an Invoice Management System expert. I would like to know the following two things.
1. On posting an 'incomming invoice' (with reference to a PO) in SRM this Invoice will be replicated to the R/3 back-end system. The back-end will and should use this invoice to follow-up the financial administrative process, how do they go about on this. The purchase order and Invoice will be posted to f.e. G/L 'Sources, with tax 19%'. What transaction do financial administrators use to book/post bank/liquid asset changes against these invoices?
2. Up on creating a credit memo, for example for 1 of the 2 line items that wern't delivered but where initially invoiced, do we need to create a Credit Memo in SRM with negative amounts or does the Credit Memo with positive amounts suffice. It will always be used as credit, positive doesn't mean it's debit? (I think credit memo's in SRM work almost the same as Credit Memo's in R/3)
Kind regards,
Tim

Answer 1

Dear all,
I answer my request, as nobody is talking about this subject.
I passed the CO certification
SAP Certified Application Associate - Management Accounting (CO) with SAP ERP 6.0 EhP6
and succeed without having SAP training, i've 4 years of SAP FICO experiences and 1 year of auditing, accounting experience.
All i've to say is to read and study many times  SAP documentation but be carreful as CO change with planning in the new ledgers and CO report, take the most updated training documentation.
My advice is to work hardly every day, even with the help of SAP training , you've to work hard, the training is just making it easy for you.
Good luck.
