Hi,

Can anyone please explain what are ACS, OLO, OLI, OLC function modules, when and why are they generated in TDMS activity ?

Thanks in Advance,

Kishore.

Hi Kishore,

These FMs are generated to perform data migration and should never be changed.

The meanings are:

OLC: Outer layer complex (Execution controller, it calls the different migration layers)

OLI: Outer layer input (FM for data reading)

OLO: Outer layer output (FM for data writing)

IL: Inner layer (FM that performs data conversion)

ACS:  Access plan calculator server

TDMS generates ACS OLI OLO and IL only if required, otherwise generic FMs are used.

TDMS activity that generates them is "Generation of Run-Time Objects for Data Transfer".
