File Merge Scenario

Dear Experts,

I need to develop a file to file scenario. Where I have to file source and one target FTP.

I will get two files from two different FTP path . Two files will have multiple records separated by new line but there will be a common parameter between this two files like below -

File1                                              File2

ID,Name,Address                            ID,Expense

1 ,ABC  , KOL                                 1 ,20000.00

2 ,DEF  , HYD                                 2 ,25000.00

3 ,PQR  ,CHN                                  4 ,30000.00

My requirement is - I need to to check the records of two file and in the target file I need to populate only those records which has common ID in both the files.

This can be done through ccBPM. But, at the time of POC I have checked that if there is any mismatch of the IDs in both the files It don't populate the target file. I have followed the conventional File Merge approach of ccBPM available in SCN posts.

Please help.

Thanks,

Apu
