tFileInputMSPositional - How to extract values from the component

Anonymous — Sat, 16 Nov 2024 13:42:58 GMT

I am Using the tFileInputMSPositional component to parse a text file which is multi schema. I able to extract those values using the tlogrow component. I am not able to extract these values from tFileInputMSPositional component to the other components as tmap. Please let me know your suggestions.
I am trying to extract header 1, header 2, body 1 and body 2 different schema values in a tmap.
Input File :
1 TEST FILE 20090724 188TEST COMPANY

Hello

I am trying to extract header 1, header 2, body 1 and body 2 different schema values in a tmap.

I think you are tring to create a cycle flow in a job. You are not allowed to create a cycle flow in a job. See 1468.

Hi Shong,
Can you please upload the image for extracting the header 1, header 2, body 1 and body 2 from tFileInputMSPositional component. The multi schema is configured in the same positional fine. Just to add header 1, header 2, body 1 and body 2 are different schema in the same file.

hi Shong
Basically, what Dinesh is asking is that we know that Multishchema component gives records of different types (row_A_1, row_B_1, row_C_1) but is there a way we can combine any two of the outputs e.g. ca we combine row_A_1 and row_B_1. If yes, how ?
Thanks

Hello

but is there a way we can combine any two of the outputs e.g. ca we combine row_A_1 and row_B_1. If yes, how ?

Because you are not allowed to create a cycle flow in a job, so as a workaround, you can output the row_A_1 and row_B_1 to two temporary files first, and in the next subjob, using two tFileInputDelimited components to read the temp files again and merge them on tMap. In a job, you can use tCreateTemporaryFile to create temp file, the file will be deleted auto when the job ends.

Is this still the case for tFileInputMSPositional? I also have a multi schema positional file but every 7 rows is one entity. So basically I have to combine all 7 rows into one row. I know that I can export them into 7 temporary files, then re-import them and join them in either tmap or tjoin...but I was hoping there is a way around this. I am not sure as to why tFileInputMSPositional still does not allow me to aggregate rows...

I decided to export all 7 rows to different csv files and input them again. My current issue is that I am not sure how to combine them in tMap.
Each of the 7 rows/outputs/inputs = 1 actual row. Do I have to create an extra column to number them in the output so that I can match them in the tmap? Any help would be great.
