I have a design PDM tool. I am searching for a utility to show comparison of data between PDM and SAP or create simple XML from selected data, elements, etc.
Since there is no exact procedure for this operation, I recommend checking the available websites listed through Google Search because this is the only way to obtain help regarding the procedure in your inquiry.
