Notes on Loading Organizational Units from
EC-CS and EC-PCA 
Supplementing the process description Loading Organizational Units from Files in EC-CS and EC-PCA in the following sections you can find information on using and Customizing the upload method.
You can use one of the following procedures for the aggregation of a profit center hierarchy from Enterprise Controlling (EC-PCA).
· You aggregate the profit center hierarchy during the data transfer to the consolidation system. For additional information, see Aggregating Master Data and Hierarchies for Transfer to SEM-BCS.
You load the consolidation groups master data for profit center consolidation from a file of type Profit Center Hierarchy from ECC(PRCGR_HIER.TXT).
If the combination of profit center and company has been defined as one characteristic with the role consolidation unit in the consolidation system, you can specify that the profit centers also become consolidation groups during the data transfer (see End Nodes in Source Hierarchy Become Consolidation Groups). In this case, the system also loads the combinations of profit centers and companies from a file of type Combination Profit Center/Company from ECC (PRCTR_COMP.TXT).

Note that the master data in the files from EC-CS and EC-PCA is not mapped in its entirety. For details of which master data the consolidation system collects see Assignments of the Files from EC-CS and EC-PCA.
If you need to, you can supplement missing information from the sender system by Flexible Upload of a simple file or by Load from Data Stream.
For profit center consolidation you load the consolidation unit master data from a file of type Combination Profit Center/Company from ECC (PRCTR_COMP.TXT).
If the combination of profit center and company has been defined as one characteristic with the role consolidation unit in the consolidation system, you can create in mapping a reusable mapping rule for the combination of profit center and company for a consolidation unit. You will require these mapping rules again when loading the consolidation unit hierarchy. For more information, see Mapping in the section Mapping Rules.
For business area consolidation you load the master data from a file of type Combination Business Area/Company from ECC (PRCTR_COMP.TXT).
If the combination of consolidation business area and company has been defined as one characteristic with the role consolidation unit in the consolidation system, you can create in mapping a reusable mapping rule for the combination of consolidation business area and company for a consolidation unit. For more information, see Mapping in the section Mapping Rules.
You load the consolidation unit hierarchy data for profit center consolidation from a file of type Profit Center Hierarchy from ECC(PRCGR_HIER.TXT).
If the combination of profit center and company has been defined as one characteristic with the role consolidation unit in the consolidation system, you load the consolidation units hierarchy from the files of type Combinations PC/Company and PC Hierarchy from ECC (PRCTR_COMP.TXT and PRCGR_HIER.TXT) You can specify that for the data transfer the profit centers also become consolidation groups (see End Nodes in Source Hierarchy Become Consolidation Groups).
You load combinations of profit centers and companies from a file of type Combination Business Area/Company from ECC (PRCTR_COMP.TXT).
You load the combinations of consolidation business areas and companies from a file of type Combination Business Area/Company from ECC(CONSBUSAREA_COMP.TXT).
