Transformation/Conversion

Hello experts.

I am working with SAP BPC MS 7.5 SP11.

I am facing a new situation in which I need to do some data conversions depending on two dimensions. I need to change the ACCOUNT but using different rules depending on the LEGALENTITY.

Initial data:

LEGALENTITY,CATEGORY,ACCOUNTL,DATASRC,VALUE

10001000,ACTUAL,100000,REPO,123456

13001310,ACTUAL,100010,REPO,456789

13001310,ACTUAL,100020,REPO,890123

13001320,ACTUAL,100010,REPO,100

13001320,ACTUAL,100020,REPO,987654

I would like to know if it is posible to handle in a single conversion file three different mapping rules. One for company 13001310, one form company 13001320 and one for all the other companies.

Result:

LEGALENTITY,CATEGORY,ACCOUNTL,DATASRC,VALUE

1000,ACTUAL,100000,REPO,123456           (shortened the legalentity and no changes in account)

1300,ACTUAL,200020,REPO,456789           (shortened  the legalentity and the accountl using mapping1)

1300,ACTUAL,200040,REPO,890123           (shortened the legalentity and the accountl using mapping1)

1300,ACTUAL,300035,REPO,100                 (shortened the legalentity and the accountl using mapping2)

1300,ACTUAL,300036,REPO,987654           (shortened the legalentity and the accountl using mapping2)

Is this posible?

Thanks very much in advance for your help!
