Link with a tHashoutput not working when one of the thashoutput has zero rows.
Version: 5.6.1 Build id: V5.6.1_20141207_1530
Although the job I am running is quite complex, here is I am providing a simple scenario: I am trying to link two thashoutput components with "Link with tHashoutput" property.
Issue:
First thashoutput (thashoutput_1)component has data (thashoutput_1.NB_LINE return number of rows).
Second thashoutput (thashoutput_2) component is linked to first thashoutput (thashoutput_1).
But, when I count the thashoutput_2.NB_LINE it returns 0 rows.
The issue occurs when we try to put the tfilterrow before thashoutput_2 and the filter does not return any rows.
you need a tHashInput component (linked to either of the HashOutputs) to read the (combined) data that these tHashOutput components wrote to the cache.
your tFilterRow_2 component "does not return any rows", yes, so the following tHashOutput_2 component has no rows to process and therefore its NB_LINE value is 0. To me this is the normal behaviour as it should be, isn't it? What should the job do if the filter before tHashOutput_2 returns no rows?
In terms of NB_LINE it will be 0 (right) . But in my job, thashoutput_2 is linked with thashoutput_1.
So , when you are connecting the tlinkhashputput_2 to tfileoutputexcel the overall output to the excel file should be the combined result of thasoutput_1 and thashoutput_2. Which is not happening.
Please check my job. Hope this would give you an idea what I was trying to highlight.
