Mismatch in SAP GTS and SAP ECC Unit of measures

Hi Experts,

we are going to implement SAP GTS for our existing two SAP ECC production servers PRD100 and PRD200. and we will connect these both SAP ECC servers with one GTS server for our trading requirements. We are facing some issues in Dimension , ISO code and UOM mismatch. Example:

Issue 1:

PRD100 has Dimension "SPEED" and SI Unit is "M/S"

PRD200 has dimension "SPEED and SI unit as "MS"

now both of these servers are going to be connected with one GTS server so for Dimension "SPEED" what should be the SI unit. or how can we handle this issue?

Issue2:

PRD100 has ISO code BD as "Board" and PRD200 has ISO code BD as "Bundle"

now both of these servers are going to be connected with one GTS server so for ISO Code "BD" how should we update it in GTS?

Issue3:

also there are differences in UOM details in both the clients. example Decimal place rounding, Dimension, ISO code, Primary code, Unit text, decimal places, etc.

could you please advise how can we solve this issue so that we can pass master data and transnational data to GTS without any error.

Thank you in advance, help really appreciated.
