0EC_PCA_1 does not bring any data

Does anybody know why the 0EC_PCA_1 does not bring any data.....even in RSA3 without any filter....ive checked the extractor and the problem is that table GLPCT is empty and extractor bring the data from it...i dont know FI but

Is there any process to fill that table?

Or its a version problem my system is a ECC 6.0

Or maybe another datasource is expected to be used in this case?

I am using the 0PCA_C01 infocube and theres no new version for it and 0EC_PCA_1 is the only one datasource for it....
