RFC Lookups vs JCO calls

[bhavesh_kantilal]

Hi,

Since Sp14 , one can do an RFC Lookup using the Lookup API and the RFC adapter for cross referencing.One can also do a JCO call directly to get the corss referencing data.

My question is ,which among the 2 approaches is a better option and why?

Looking forward to some valuable tips and information,

Hi Bhavesh,

I guess JCo calls are used more so for executing calls to an application system

Hi,

RFC adapter is also internally might be using LIBRFC32.

The RFC call is JCO based.

Can't say which one is faster but it's always better to go with the standard as this will help you in maintenance and durin upgrade of your product.

Hi,

If you are using direct JCO calls then you are hardcoding the system and user id details in your code. thats the reason SAP came up with lookup.

If any of the parameter changes you just have to change in one place rather then touching the code.

A neater way to do it.
