Hi Experts,
In our case we are using vertex to calculate taxes. In ECC if I create a order external system vertex is called through the RFC RFC_CALCULATE_TAXES_DOC and tax is calculated successfully. External system is called at the time of after save only.
But in CRM system, if I create a order external system has not been called. The tax settings are maintained properly for TTE using external system.
In CRM system while adding the item itself tax is calculated from the IPC system. After the call of RFC SPC_GET_PRICING_DOCUMENT_INF all the pricing are calculated including Tax. But according to me it should go to External system for tax calculation.
I have tried to track the log message using sm53. There I getting error message as "client is null in releaseClient Stack trace of the call" under /applicationn/system/. But there is no log for external tax call.
Please provide me the reason why it is not calling external system.
Thanks,
Vignesh
