[Help] Warnings about metal layers in .map file

$

Hello All,

I need your suggestions the warnings I got in the report after P&R with Encounter. The warning information is as following:

Parse map file...

**WARN: (ENCOGDS-399):   Only 2 layer(s) (M2 M3) of a VIAFILL object is(are) specified in map file 'tsmc090.map'. A VIAFILL object needs 3 layers (M2 VIA2 M3) being specified at the same time in the map file. Add VIAFILL contruct(s) to the map file for the following layer(s): VIA2 or remove VIAFILL construct(s) from the map file for the following layer(s): M2 M3.
 **WARN: (ENCOGDS-399):   Only 2 layer(s) (M2 M3) of a VIAFILLOPC object is(are) specified in map file 'tsmc090.map'. A VIAFILLOPC object needs 3 layers (M2 VIA2 M3) being specified at the same time in the map file. Add VIAFILLOPC contruct(s) to the map file for the following layer(s): VIA2 or remove VIAFILLOPC construct(s) from the map file for the following layer(s): M2 M3
.

As the warning suggested, I should add  Add VIAFILL contruct(s) to the map file for the following layer(s): VIA2. I don't know how to add VIAFILL only to VIA2. I tried to change VIA1 with ALL layers, shown with underline. The warning information for M1 and M2 went away.

#-------------------------------------------------------------------------------
#SOC Layer Name   SOC Layer Type   GDS Layer Number   GDS Layer Type
#==============   ==============   ================   ==============

 #VIA1              VIA              51                 0   

VIA1              ALL              51                 0

 

Question: I am nor sure whether the way I updated the .map file is correct or not although the warning information does disappear. Could you please tell me how to do this correctly, or any reference to generate correct .map file? 

 

Thank you, and the .map file I am using is as following:

 

The information in the .map file: (tsmc90)
