The problem is that the CRM datasource 0crm_sales_contr_i (contracts) can't capture delta. The steps to reporduce the problem:
1.- In BW we launch the delta initialization infopackage, and it loads all contracts that are in CRM.
2.- Then, in CRM we go to RSA7, and we see here the datasource 0crm_sales_contr_i.
3.- Go to CRM, create a new contract and save it.
4.- Now, after create a new contract, in the RSA7 the number of records of the 0crm_sales_contr_i has not increased. It stays to zero.
5.- Finally, we launch de delta infopackage, and it loads 0 records.
Any comments should be highly appreciated!
