Issue in tmap

Anonymous — Fri, 31 May 2019 13:41:34 GMT

Hello!

I have one mapping issue. The issue goes like:

I have a fact table:

fact id	Element_id	B_type
1	23.A01-01-PV	15
2	23.A02-01-PV	15
3	23.A03-01-PV	20

Then I have a rule table like:

Rule id	filter element id	Filter B_type
1	23.A	15
2	23.A01	15
3	23.A02-01-PV	15

I want to create an X-ref table between both of them. For this I need to comapre the pattern in rule table and use the Filter B_type.

Final Output:

fact id	Rule id
1	1
1	2
2	1
2	3

To comapre the strings, I broke element_id in both the tables in TMap like following

Fact Table:

Element_id	Bdel	Group	Undergroup	LNO	Component
23.A01-01-PV	23	A	01	01	PV
23.A02-01-PV	23	A	02	01	PV
23.A03-01-PV	23	A	03	01	PV

Rule Table:

filter element id	Bdel	Group	Undergroup	LNO	Component
23.A	23	A	Null	Null	Null
23.A01	23	A	01	Null	Null
23.A02-01-PV	23	A	02	01	PV

Unfortunately now I am stuck. I dont know how to comapre these two in TMap to produce the Final output mentioned above.

How can I do it?

Regards

Hi Priya,

I hope the below solution will help you (Note:- In your sample output, you did not mention the combination for fact_id 3. I hope it was accidental)

Please refer the tMap details below.

row3.element_id.contains(row4.filter_element_id)

On a lighter note, I hope your team members looking for regular expression won't complain this time

Warm Regards,

Hello @nthampi !

Thank you so much for your reply. The solution works but fails when I add a condition. As you can see in the example, there is one more filter called Filter B_TYPE. So in the expression filter, I added this

row3.element_id.contains(row4_Element.FILTER_ELEMENT_ID) && row3.type.equals( row4_Element.FILTER_B_TYPE). Is it not correct?

Regards

Priya

Hi,

It worked fine for me!

row1.Element_id.contains(row2.filter_element_id) && row1.B_type.equals( row2.Filter_B_type)

Please check whether you are adding variables in right case. That could be the reason.

We have resolved both your original and supplementary query now 🙂 If all looks fine, please spare a second to mark the topic as resolved.
