AddGenConstrIndicator coefficients are high
Awaiting user input
In MPS file I am seeing coefficients of e+05.
C55798(6) gen282 -1.1748062592941143e+05
C55798(6) gen283 -1.1748062592941143e+05
C55873(6) gen282 -3.5745765630245427e+04
C55873(6) gen283 -3.5745765630245427e+04
C55882(6) gen282 -2.3122216621734641e+05
C55882(6) gen283 -2.3122216621734641e+05
Coefficient statistics:
Matrix range [1e-03, 5e+03]
Objective range [1e+00, 1e+01]
Bounds range [1e-04, 1e+04]
RHS range [1e+00, 5e+03]
GenCon rhs range [3e-01, 4e+03]
GenCon coe range [1e-01, 8e+05]
I have couple of questions
1) Is there a way to reduce this GenCon coe range ?
2) From MPS file how to figure out which constraint is exactly, since here the constraint are numbered and in lp file we can't see the GenCon coefficients. So how to figure out based on MPS file which constraint is this?

In the MPS file you should see a GENCONS section, see MPS format. This should allow you to figure out what the general constraint is.
It is similar in an LP file, see LP format,e.g.,
GC0: C1 = 1 -> 10000 C0 = 3
Does this help?
You could also share the MPS file or the LP file for easier exchange. Note that uploading files in the Community Forum is not possible but we discuss an alternative in Posting to the Community Forum.
