PCA datasource

Question

Have you used the following datasource before?
1) 0EC_PCA_1 (provides summary records for all profit and loss accounts (cost elements) and balance sheet accounts which are transferred to Profit Center Accounting)
2) 0EC_PCA_3 (transfer structure in the OLAP system does not use the following key fields)
I dont have much knowlege on the FI, not sure exactly what's the difference between above 2 datasource and which one should be use for which scenario.
Can you please help, thanks.

Answer 1

U do not have 'Balance' field in 0EC_PCA_3, it has only credit and debit. At this line item level 'Balance' stands for (Credit +/- Debit).
where as 0EC_PCA_1 extractor maintains 'Cumulative Balance (0Balance)' logic with carryforward.
Its good to use 0EC_PCA_1 for 'Totals' (consolidate) reports.
If u need Line Item reports, then u should create DSO on top of 0EC_PCA_3, and create Line Item reports on DSO.
In that way u can always drill down from 'totals' report to Line item reports using RRI.
If u check PCA standard queries (in SAP help), most of the reports defined on 0PCA_C01 ( from 0EC_PCA_1).
Yes... the posting in other applications (SD, MM) would populate figures for Profit center depends on configuration.
