Exception in component tMap_15 (Interceramic)
java.lang.NullPointerException
at local_project.interceramic_0_1.Interceramic.tFileInputExcel_5Process(Interceramic.java:24184)

Hi,
You are getting the Null pointer excpetion in tMp. Could you please share the overall job flow and the screen shot of the tMap so that we will get more idea about what you are trying to achieve?

Hi, Nikhil Thampi
Of Course
Job.jpg is the image where show the connection to join data
tMap.jpg is the connection I have with the tUnited and how I connect both of them by "No_Cntr_" and "No_Contenedor", "No_Cntr_" has black values
Salida.jpg shows one example that how data is, the red line shows column "No_Cntr_" and the rows are empty.

Hi,
I dont think that is the reason for null pointer exception. Are you using any functions or expressions in the tMap_15 (Interceramic)?
If you are using any Java function like sub string, equals etc. for a column containing null value, it will throw this error.

Hi.
According to your message, I don't use any function or expressions in tMap_15, expressions I used in tMap before to standardize each column but in tMap_15 don't; tMap_15 I'm ussing only to join both tUnite_1 (row 28) and tUnite_5 (row 44)
To answerer the second point, the column named "No_Cntr_" doesn't ussing any expression or function 'cause is a unique value and the way we received data is the same and that column is the key to integrated all data in one DB.
Regards.
And I don't know if when I want to join tUnite_1 and tUnite_5 the black values to has the column "No_Cntr_" to the output tUnited_1 be the problem because it does not have any value in tUnique_5 to joined.
