Passing values through RFC

Former Member — Sat, 01 Oct 2011 01:16:46 GMT

Hi All,

I have a requirement where we need to connect to a different system using RFC and pass data.

I have data in the table . The requirement is using RFC, i have to write a code, so that i can send all the possible values of a field in the table to the remote system. I have 5 fields in my table in SAP. First i need to pass all the possible values of field1 to the remote system and based on the input in their system, i need to pass all possible values for field2 to remote system and again based on field1 and field2 i need to pass all possible values for field3 to remote system.

Pls let me know how to do coding for this.

Thanks,

Raju

Hi Raj,

Welcome to scn.Can you explain what is the business requirement and which data you want send with this validation.

Hi Madhu,

We have one custom table in SAP which has 5 fields.

In remote system, they will have a form which needs to be filled by user. This form has the 5 fields that are in the custom table.

We need to pass the possible values from our custom table to the remote system, so that the user can see all the possible values for the fields. Similar to the F4 option.

And based on field1 input in the form by the user, we need to get corresponding values for field2 of all possible values and pass it to the remote system.

Thanks,

Raj

Hi Raj,

It is fine getting f4 values and all is easy.I want know how you are going to relate those two fields .If you see in va02 depending on we will get sales group values depending on sales office.You just how you are going to match .Check this and post.

Madhu.

If your user is filling the forms in the non-SAP system itself, means you are just providing the data to that system for the actual user action there. So, either you can send the whole data everytime and let non-sap system handle the logic which you need for the possible values for each selection. Better if you are able to store all data in the remote system itself to avoid large data communication everytime and just sync the 2 systems whenever something changes in SAP.

Otherwise, if you want to control it from SAP itself, then you need 2 way communication.....once user fills 1st field in FORM, remote system sends that to SAP and then you send the 2nd field valid values to remote system again using same/different RFC and so on. But, I doubt that will be efficient for the user filling the form.

Hi Raj,

Actually yop have to cretae two way communication. It is nothing, First you have to ctreate one table(What are all the field you want send to other system) and ctretae another table (What are all the fields value getting from other System) this tables should be mentioned in table tab in function module.

same structuer should be declard in other system (Type of field and field length should be same), Then fir example if other system is .NET, Now we have to create proxy and the you can get it. (Using SAP .NET connector)

Thanks

Hi Raj,

What Diwakar is saying is correct,itwill be better if you can syncronize both the systems.

Else, You can create BAPI which will be communicating both systems.

This BAPI will get the first field in case it is field and then calculate and provide the second field accordingly.

Hi,

You can use this for your reference:

/SAPSLL/IFEX_SD0A_R3 this BADI is generally used to transfer data or you can always create your custom RFC and transfer the data.

Hi Raj,

You have two options.

1) Load all data from SAP custom table by triggering the RFC in NON SAP system in very beginning you call this non sap application and ask you technical consultant who is working on non sap system, to use those data as your search help based on selection critaria

2) Create two way RFC which will accept input from non sap system and based on the critaria fetch details from SAP and transfer it back to the non sap system.

1st option is advisable only if records you are going to fetch from SAP is very less (e.g some master record with abount 0 to 200 entries) becasue incase of very huge data, it may reduce performance of your non sap application so badly.

else go for 2nd option which is again little performance reducive but still advisable since will take always same kind of time and will not effect your application so badly as there will be a selection critaria so time will be consumed what it takes for connection between systems.
