Converting UoM's from Imperial to Metric between SAP and GTS

[Former Member]

We have tried multiple approaches to convert UoM's from Imperial (Base & Sales Unit) to Metric between SAP and GTS. We have not been able to successfully convert from 'FT' in ECC to 'MM' in GTS (as an example). We've looked at setting the Alternate UoM in GTS, using SAP Function Modules, External UoM's (using relevant FTO), and even tried creating a Custom z-table to convert the UoM at GR. However, every time we process a receipt in the 'Metric' location, the Imperial UoM remains; and the subsequent GTS reporting stays in the Base (Imperial) UoM instead of Metric.

So, what are the steps to convert parts from Imperial to Metric UoM in GTS? Where parts are Purchased, Received, Stocked, and Sold in Imperial (i.e. 'FT'), but GTS / Customs outputs (reports, e-filing) are in metric (i.e. 'MM')? Can this be done with Standard SAP? Where do we maintain this conversion?

Hi Aaron,

You would need to transform the Base UoM in the BAdIs, for the Product Master record and transactions.

For the Product Master record transfers, code the BAdI /SAPSLL/IS_MATMAS_R3, Method PI_IS_MAT_MAP_001, or User-exit SLL_LEG_PRR3_004.

For the transactional transfers, code the BAdIs /SAPSLL/IFEX_MM0A_R3, .._MM0C_R3, etc.

Hope that helps.

Thank you Dean for you reply. However, we did try that - with metric in the ECC Material Master and corresponding Metric conversion in GTS Master data as well (as you stated, they are replicated). Unfortunately the UoM still doesn't get converted..... basically because I think GTS doesn't know that it 'should' convert the UoM. Do we need to set desired UoM's at the receiving FTO to trigger the conversion? Currently there's nothing that 'tells' the system to convert the UoM to metric.

That is Unit Of Measure tab in Material Master. Discounting the Supplemental UOM, all of the conversions should be maintained in the Material Master. These conversions are replicated to GTS when the material is transferred.

I hope this helps.
