Updating the job attributes and Position attributes - Infotypes 1610 and 1613

Hello Experts,

We have a requirement to update the job attributes and position attributes from a custom program (i.e. excel file). We tried using the BDC option but it was quite unstable Some times it goes and enters the attributes properly but some times it goes to some other screen where in we have to enter the new entries button manually and hence the bdc is getting failed.

Also we tried using the function modules RH_PNNNN_MAINTAIN but it is of no help.

Any inputs are really helpful.

Thanks,

Sanath.
